摘要： PURPOSE:To increase the usable temperature range by compensating the volume change of a sealing chamber due to linear expansion coefficient different of a casing and a piezoelectric element by the volume change of liquid in the chamber. CONSTITUTION:A piezoelectric element 1 is disposed in a casing 2, its one end is secured to a stopper 7, and the other end is contacted fixedly with a piston 8 to transmit the axial elongating or contracting displacement to the piston 8. Silicon oil is sealed in a space formed of the piston 8, and a bottomed cylinder 2a to form a sealing chamber 10. A through hole 12 of small diameter is formed by a piston 8 which communicates with the chamber 10 in the casing 2, and the rod 3 of an output member is slidably provided therein. The rod 3 is energized by a spring 4 supported by a stopper 9 to the chamber 10 side to apply a pressure to the oil. Thus, the volume change of the chamber 10 due to the difference of the linear expansion coefficients of the casing 2 and the element 1 is brought into coincidence with the volume change of the oil and compensated.
